Operating Temperature
High Temperature Threshold (deg. C).
A message (up to 7 characters) is output
whenever the temperature exceeds the set threshold. The message repeats one time
every 30 minutes until the over temperature condition is eliminated. If the tempera-
ture threshold is set to zero, then the over-temperature message will be disabled.
Low Temperature Threshold (deg. C)
. A message (up to 7 characters) is output when-
ever the temperature falls below the set threshold. The message repeats one time
every 30 minutes until the low temperature condition is eliminated. If the tempera-
ture threshold is set to zero, then the low-temperature message will be disabled.
Lifetime
Lifetime Hours (x 10). Allows you to set the target value of the Lifetime Threshold.
Lifetime Message
. Allows you to create a message that will appear whenever the
threshold is reached or exceeded.
Present Operating Temperature (deg. C)
Not adjustable.
Product internal temperature is read by a thermal sensor on the main PCB, then a
case-differential constant is subtracted in order to give an estimated external temper-
ature.
Counts
Not adjustable.
Powerups
:
Reports the total number of “cold” resets (w/RAM contents not already ini-
tialized at reset).
Resets
:
Reports the total number of “warm” resets (w/RAM contents already initialized at
reset). Warm resets include watchdog timer and commands <A>, <Z>, and <d>.
Time Since Last Reset
Reports the number of hours and minutes of operation since the last system reset.
Not adjustable. This is useful for detecting unwanted resets caused by power supply
problems or ESD transients.
